This is the first study to examine characteristics, motivations and experiences of Indian egg donors. In-depth interviews were conducted with 25 egg donors who had donated during the previous 8 months at a fertility clinic in Mumbai. The semi-structured interviews were conducted in Hindi and English. In addition to demographic information, data were collected on donors' motivations for donating...

Species-specific differences in the responses of egg-laying mosquitoes (Diptera: Culicidae) to the presence of fish exudates in oviposition sites in laboratory bioassays have been related to the likelihood of encountering mosquito-eating fish in natural oviposition sites. We examined the responses of egg-laying mosquitoes to the presence of larvivorous fish in oviposition sites to test this hyp...

When Bacillus anthracis is grown in egg yolk medium, a reaction occurs which is presumably due to lecithinase (Colmer, 1948; McGaughey and Chu, 1948; Chu, 1949). In liquid egg yolk medium the lecithinase reaction is characterized by the formation of an opalescent suspension and flocculation of particles which rise to the top of the medium as a curd. A test such as this is usually referred to as...

Aim of the present study was the comparative evaluation of the effect of ground oregano, anise and olive leaves as feed additives on performance and some egg quality characteristics of laying Japanese quails. A total of 189 Coturnix japonica quails (126 females and 63 males), 149 days old, were randomly allocated into seven equal groups with three subgroups of 9 birds each (6 females and 3 male...

The current study was done in the hatchery unit/ animal production department/ directorate of agricultural research Sulaimani province from 28 March – 7 May 2022. Three hundred (300) eggs were used to effect egg shape parameters on characteristics hatched chicks. Immediately after collecting eggs, weighted by using electronic balance (0.01 g) sensitive, and length Breadth for each measured digi...

Environ. Entomol. 15: 501-506 (1986) ABSTRACT Studies were conducted in commercial sweet corn fields in upstate New York to collect information for developing a sampling protocol for egg masses and larvae of European corn borer (ECB), Ostrinia nubilalis (Hubner). Information was collected on 1) aggregation of populations in portions of the field (e.g., aggregation along borders), 2) distributio...

Experimental infections of Egyptian Radix natalensis (shell height at miracidial exposure: 4 mm) with a French isolate of Fasciola hepatica were carried out under laboratory conditions at 22 °C to specify the characteristics and follow the dynamics of their egg-laying. Controls constituted unexposed R. natalensis of the same size. No significant difference between controls and the uninfected sn...

Step-Up Protein (SUP) rearing regimens can reduce Feed Consumption (FC) and Body Weight (BW), while still resulting in pullets with equal or superior egg production and egg mass to pullets grown on a Step-Down Protein (SDP) program. Egg weight has been reduced due to SUP programs, presumably due to the reduced BW at sexual maturity. Because BW is reduced by SUP regimens and a slight lowering of...

Recently, many avian antimicrobial peptides have been predicted by bioinformatics and identified by proteomics. These compounds are generally small cationic molecules that possess activities against protozoans, fungi and viruses, as well as gram-positive and gram-negative bacteria. They are components of innate immunity and are capable of evading pathogen resistance mechanisms. Hens export prot...

A commercial egg-type chicken (ISA Brown; CEC) and a dual-purpose pure breed of the Korean Native Chicken (KNC) were compared for yolk to albumen (Y:A) ratio and their major egg characteristics at seven different ages. The eggs from KNC were significantly (P < 0.01) lighter in egg, albumen, and shell weight than those from CEC. However, the yolk weight and Y:A ratio of the eggs from KNC were si...
